geode: Avoid reading /dev/cpu/0/msr, which does not exist.

This is another sneaky patch posted online by RVP.

XXX it should be verified whether changing _PATH_MSRDEV to /dev/cpuctl
works on NetBSD (instead of this patch), but for now this is known to
work. I don't have access to the hardware to test an alternative
solution (neither does RVP).

merge xf86-video-geode 2.11.21, xf86-video-i128 1.4.1,
xf86-video-neomagic 1.3.1, and xf86-video-savage 2.4.0.

initial import of xf86-video-geode-2.11.21

Avoid multiple definitions of the same variable.

merge xf86-video-ati 19.1.0, xf86-video-amdgpu 19.1.0,
xf86-video-geode 2.11.20, and xf86-video-s3 0.7.0.

initial import of xf86-video-geode-2.11.20

fix various errors and warnings with xorg-server 1.20:

- no Error() in scope
- more wakeup/blockhandler ABI changes
- more notify fd API changes
- more xf86CursorResetCursor changes
- lots of char* -> const char*
- fix ati kms config.h now HAVE_XF86_CURSOR_RESET_CURSOR is available
- another xf86GetOS() is removed fix
- OsBlockSIGIO() etc, -> old, but still around API until properly converted
- don't free const char * data owned by some other system

various updates for xorg-server 1.20. some of these are work-in-progress,
the xsrc build is broken for most ports currently.

- xf86DisableRandR() is gone
- use HAVE_NOTIFY_FD like other modern drivers in compat-api.h
- pRotatedPixmap is done
- some PixmanPtr is now DrawablePtr (this one is all over problem with many
consumers, and perhaps the major breakage point currently.)

need to include xorg-server.h

initial import of xf86-video-geode-2.11.19

remove xorg-server.h from all the places we added it recently, as this
problem is now fixed more generally and globally.

merge xf86-video-geode 2.11.18, xf86-video-openchrome 0.4.0,
xf86-video-rendition 4.2.6, and xf86-video-s3virge 1.10.7.

initial import of xf86-video-geode-2.11.18

include xorg-server.h which is normally included by config.h.

(this change isn't a candidate for upstream.)

make this work in a config.h-less way.

merge xf86-video- ast 1.0.1, cirrus 1.5.3, geode 2.11.17, mach64 6.9.5,
savage 2.3.8 and siliconmotion 1.7.8.

initial import of xf86-video-geode-2.11.17

Fix i386 build - reported and tested by Hisashi T Fujinaka

re-do the previous correctly.

merge xf86-video-geode 2.11.15.

initial import of xf86-video-geode-2.11.15

Revert previous, -Dlseek64=lseek added to
src/external/mit/xorg/server/drivers/xf86-video-geode/Makefile

Add:
#define lseek64 lseek
so this builds.
Has NetBSD ever had an lseek64 - there isn't one in libc - so has this
code ever actually run.

update this for xf86-video-geode 2.11.12

initial import of xf86-video-geode-2.11.12:
- fixes corrupted overlap issues
- fixes for some particular panels

update this for xf86-video-geode 2.11.10

initial import of xf86-video-geode-2.11.10

geode wants a config.h. give it one.
